What function do you use to read from a file in C?

The function used to read from a file in C is commonly fscanf() or fgets(). These functions are designed specifically to handle input from files.

This function will parse the input data according to the format specifiers you provide, enabling you to extract integers, floats, characters, strings, and other types of data directly from the file.

On the other hand, fgets() is used to read an entire line from a specified file stream, which is useful when you want to capture a whole line of text, including spaces, until a newline character is encountered or the end of the file is reached. This function ensures that you retrieve full lines efficiently without breaking them into tokens.

The other options do not serve the purpose of reading from a file. fopen() is used to open files and associates them with a file stream, fwrite() is intended for writing data to a file, and fprintf() is used for formatted output to a file. Thus, when it comes to reading data from a file in C, `fscanf
